This VAT Configuration module allows you to configure types of VAT that have varying VAT values over time. It has come to light that in a number of applications VAT configuration is underestimated and included as an attribute of an entity (e.g. a product). This can lead to complications when the VAT amount can vary over time and the amount will change in the future. This module offers a mechanism to define a time span where a certain VAT amount holds. The mechanism ensures that time spans are not overlapping and cover the whole future time span. The VAT amount on a certain date can easily be retrieved by using the GetVATAmount microflow and giving the VAT type and the date as input.
